Would Buy Again
I am using this to treat camallanus worms in my family's aquariums, and it is apparently effective. I get nervous buying medication from unknown brands, but this appears to be the real deal. The species it's unsafe with really should be on the description instead of just the bottle, but in our case it didn't matter because levamisole is the ONLY freshwater treatment for these worms. Fenbendazole makes them retreat, but they just come right back.
